Question

In a particular species of fox, coat color can be silverish blue, red or brown. When pure-breeding foxes with silverish blue coats are mated with pure-breeding foxes with red coats, all F1 progeny have red coats. Mating F1 foxes produces 104 foxes with red coats, 78 foxes with brown coats, and 12 foxes with silverfish blue coats. Based on the observed data, what is the most likely genetic basis for the inheritance of coat color in foxes?

a. multiple alleles

b. simple gene interaction

c. epistasis

d. incomplete dominance

e. codominance

f. sex linkage

Explanation / Answer

Answer is epistasis. Since in epistasis expression of one gene is governed by another gene, majorly the effect will be observed in F2 progeny.
